Question v-Server: Reverse DNS does not match SMTP Banner

[Xavier]

Hi
on a v-server I run 2 domains with their individial ip-addresses. Each domain has its own mailserver. When I check those email servers via mxtoolbox.com I get following errors:

SMTP Banner Check: Reverse DNS does not match SMTP Banner
SMTP Valid Hostname : Reverse DNS is not a valid Hostname

How can these problems solved?

I was googling a lot but could not find a working solution.

Unless you have an option to add Reverse DNS from your VPS Hosting Control Panel by yourself, you can ask your VPS provider to add Reverse DNS for the each IPs.

IP xxx.xxx.xxx.xxx > server.hostname.tld
